SAW.

SPECIFICATION :forming part of Letters Patent No. 307,616, dated November 4, 1884;

Application led September 6, 1884. (No model.)

To @ZZ 'wh/0m, t may concern,.-

Beit known thatI, HIRAM ALLEY, of Glifty, in the county of Decatur and State ot' India-na, have invented certain new and useful Improvements in Planning-Saws; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which-- Figure l is a side view of my improved planing-saw. Fig. 2 is a perspective view of a portion of the same, and Fig. 3 is a plan view of the'portion shown in Figf).

The same letters refer to the same parts in all the figures.

This invention relates to circular and other saws; and it has for its object to so construct the same that the stuff sawed thereby shall present smooth or planed surfaces.

To this end the invention consists in the i111- proved construction ot' the said saws which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A designates the body of my improved saw, which, in the figures, is illustrated as being a circular saw. Every alternate tooth of the said saw is an ordinary rip-tooth, while the intermediate teeth are constructed with'inclined points, inclined in the direction of the draft, and having beveled edges D D, which are beveled alternately in opposite direction. By this construction it will be seenthat the points ofthe rippingteeth C C are the longest, and serve to cut the fiber of the wood in advance of the planingteeth B B, the beveled edges of which serve as clearers, and leave the surfaces of the stuff smooth and clean and free from splinters.

This invention is, as will be easily seen, applicable to ripsaws of all kinds, whether circular or otherwise, and to saws having insertible as well as stationary teeth. The device is inexpensive, and it will run with little power and produce good results.

I am aware that it is not new to construct a saw with planing-teeth disposed alternately with the ripping-teeth; but my saw differs from others of the same class in this, that it maybe made from a saw of ordinary construe tion by truncating alternate teeth and beveling the truncated points alternately in oppo site directions.

In very heavy saws the planer-teeth may be used with central longitudinal grooves, so as to present cutting-edges on both sides.

Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United States An improved saw having all its teeth of even pitch, with every alternate tooth having its point cut ot't, and the truncated top beveled alternately in opposite directions, as shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

HIRAM ALLEY.
